To all whom it may concern: vided with an extei'ioily threaded outer end Be it known that We, HARRY WV. MAsoN adapted to receive a steam controlling valve and WILLiAlit DONNELLY, citizens of the heifeineftei." described. Arranged Within the United States, residing at San Francisco, steam conducting pipe 10' and extending in the county 01"- Sen Francisco and State across the passage 2 in the fitting is on oil, 5 of Gelifornie, have invented certain new conducting pipe 11, said pipe being oi. less and useful improvements in UiLBnrncrs; diameter than the steam pipe whereby e and We do declare the following to be e space is formed between said pipes otsiiiilfull, elem", and exact description of the in cient size to permit the passage oi steam vention, such as will enable otheis skilled through the pipe 10. The inner end of the @5 the art to which it eppetteinsto nialtc oil conducting pipe 11 has a screw threaded end use the engagement with a soeltet 12 formed in the This inve .tion to improvements in fitting l in the rear of the inner end of the oil i steem passage 2 and communicating with 355 The object t'o i'irovide an improved cone the oil 3 as shown. The oil conductstreet n of Vi the burning tuel pipe 11. is of slightly greater lfillgtll 1 ports the the box and than the steam pipe 10 and projects e slightheving means it e elay the valve may he distance be} end the same for a purpose conveniently rega ed. described. v

With this "d otte objects in View, the (in the threaded outer end of the steam invention l .tziin. novei features conducting pipe l0 is arranged a tubular of constioctiozi ce-tiers. and arrange ejylindricel steam controlling; valve 13, on ment of Wilt he more fully the outer end of which 18 formed an inscribed xilerly pointed out in the Werdly projecting amulet-flange 14 having eppendee: q beveled or inclinedihnei Wall. 15, which 39 in the scctnn onying di'ewings: Figure l is adopted to' be drawn into engagement at side View o" homer constructed in so" with a tapered e: inclined t 16 formed eordenee W invention; Fi 2 is e, on a sleeve or nipple 17 listing o screw cente s 5 section of tie seine; threaded engagement With the outer end'o't dtl otionel v ew on the line the 0d conducting tube as shown.

. on A'rriiiiged in end extending through the ten, '1 conducting pipe oil pipe 11 is the stem'19 of anoil controlling ed lehgth and is pr0- valve 20, which is in the form oil 21 comically shaped or tapered head and which is adapted to be moved into and out of engagement \vitha valve seat 21 formedby reaming out the outer end of the sleeve 17 through which the valve stem 19 projects. (in the outer end of the valve 20 is dctachably secured a fuel spreading and atomizing plate 22, said plate having a beveled outer edge which projects to a greater or less distance beyond the edges of the valve 20 and forms the means for deflecting the oil and steam and thoroughly atomizing the-same. The plate 22 is detachably seemed to the outer surface of the valve 20 by means of a fastening screw 23 or other suitable device whereby said plate may be removed and a larger or smaller plate applied to the valve to spread the burning fuel to a greater or less extent. The inner end of the stem 19 of the oil valve passes through the longitudinal bore of the fitting 1 and through a block 24. and stuffing box 25 arraing'ed on the inner end of the fitting, and has on its inner end a knob or handle 26 whereby the oil valve 20 may be regulated to permit the discharge of a greater or less amount of oil from the oil pipe. By thus arranging the steam and oil valves the same may be regulated to permit theproper relative discharge of steam and oil from the burner, thus obtaining a perfect combustion of the fuel and providing for the economical use of the latter. ,The sleeve 17 containing the steam and oil 'valve. seats is provided on itsouter surface with a series of radially projecting spacing lugs 27 whereby said sleeve is centered in the valve 13, which will prevent the sleeve from interfering with the free passage of the steam when the. valve is in an open position.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiringa more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the .principle or sacrificing any'of the advantages of the invention as defined in the ap-- pended claims.

' Having thus described our invention, what we claim is: v

1. An oil burner comprising a fitting having oppositely disposed steam and. oil inlet, massages, a, longitudinally adjustable steam- "conductingpipe threaded to one end of said fitting and communicating with the steam inlet passage therein, an oil-conducting pipe arranged within the steam pipe and connected with the oil. inlet passage in said fitting, a sleev arranged on the outer end of said oil-conducting pipe. said sleeve having its outer end internally beveled to form an oil valve seat and having an externally disposed beveled shoulder to form a steam valve seat, a tubular steam valve arranged on the outer end of said steam-conducting pipe and having on its outer end an internal annular flange adapted to eoact with the steam valve seat of said sleeve, a valve'stem ar aligned in and extending through said oil pipe, :1. flared oil valve on the outer end of said stem adapted to coact with the oil valve seat of said sleeve. and means to adjust said steam valve and said oil valve to control thedischarge of steam and oil. p

2. An oil burner comprising a fitting having steam and oil inlet passages formed therein, a longitudinally adjustable steamconducting pipe threaded to one end of said fitting and communicating with the steam passage therein, an oil-conducting pipe of less diameter than said steam pipe arranged therein and secured within the fitting to con'mmnicate with the oil inlet passage therein. a sleeve arranged on the outer end of said oilconducting pipe, said sleeve having a beveled end to form an internal valve seat: and a beveled shoulder forming an external valve seat. a tubular steam valve arranged on the. outer end of said steam-conducting pipe and having ,on its outer end an external annular flange adapted to coact with the external valve seat of said sleeve, a valve stem aranged in and extending through said oil pipe, an oil valve on the outer end of said stem adapted to coach with the external valve seat of said valve, a. flared spreader-plate secured to the outer side of said oil valve and extending beyond the burner, a. stuffing box on the steam-conducting pipe at its connection with the fitting,

a handle connected with said steam pipe, a

stufling box arranged on the outer end of the fitting around the valve stem, and ahandle secured to said stem.

In testimony whereof we have hereunto set our hands in presence of two subscrib' ing witnesses.
